QVision Operations and Installation Guide 2-2
CONNECTING THE MONITOR
TO A COMPUTER
To connect the monitor to your COMPAQ computer (or to any VGA-type
15-pin connector), follow these steps:
1. Locate the power switch on the lower right side of the monitor face.
Ensure that the power switch is in the OFF (O) position.
CAUTION: Electrostatic discharge (ESD) can damage
electronic components. Ensure that you are properly
grounded before beginning this procedure. See Appendix C
for ESD information.
Monitor Power Switch and Ventilation Slots
QVision Operations and Installation Guide 2-3
WARNING: To prevent possible damage to the video
graphic controller board, both the computer and monitor
must be OFF before connecting or disconnecting the signal
cable.
Power and Signal Cables
2. Place the monitor in a convenient, well-ventilated location near your
computer. The monitor cabinet has ventilation slots to prevent it from
overheating. Be sure nothing blocks these ventilation slots.
3. Connect the monitor contact end of the power cable to the connector
on the back of the monitor.
QVision Operations and Installation Guide 2-4
4. Connect the 5 BNC connectors from the signal cable to the monitor.
Push in and twist the connectors clockwise until they are locked into
place.
The BNC connectors are color-coded from left to right in the
following order:
White for horizontal sync (H)
Black for vertical sync (V)
Red (R)
Green (G)
Blue (B) for the video connectors.
Red, green, and blue represent the video connectors.

QVision Operations and Installation Guide 2-5
5. Connect the other end of the signal cable to the 15-pin video graphics
connector on the back of your computer.
Connecting the Graphic Signal Cable to the 15-Pin Connector
6. Secure the signal cable in place by tightening the screws on the
connector by hand.
7. Plug the AC contact end of the power cable into the AC outlet.
QVision Operations and Installation Guide 2-6
OPERATING THE MONITOR
Software applications use drivers to tell the graphics controller installed
in your computer which mode to use for any application. The graphics
controller, in turn, sends the appropriate signal to the monitor. The
QVision Graphics System from Compaq will automatically change
modes when your system changes applications.
Pre-Set Modes
The factory default or pre-set modes are the most commonly used modes.
The monitor automatically recognizes these modes when they are
requested.
Pre-Set Modes
1024 x 768 at 72 Hz 1024 x 768 at 66 Hz
640 x 480 at 60 Hz 640 x 480 at 75 Hz
720 x 400 at 70 Hz 512 x 480 at 72 Hz
640 x 350 at 70Hz
User-Modes
Occasionally, the graphics controller signal may call for a mode that was
not pre-set or previously used. This may happen for one of the following
reasons:
§ you are not using a COMPAQ standard graphics adapter
§ you are not using a pre-set mode (even with a COMPAQ graphics
adapter)
In these cases, you should re-adjust the size and centering of the monitor.
It will automatically store the new setting as a user-mode. Then, the
monitor will automatically recognize the new user-mode as it would a
pre-set mode.
QVision Operations and Installation Guide 2-7
Storing Modes
The monitor stores up to six user modes. When this limit is exceeded, the
monitor replaces the first mode that was entered (first in, first out).
Whenever you adjust the size and centering controls, these settings are
stored in one of the following:
§ The appropriate pre-set mode
§ An existing user-mode
§ A new user mode
QVision Operations and Installation Guide 2-8
Controls and Indicators
Controls and indicators are grouped along the lower front edge of the
monitor. Each has only one function, indicated by the icon on its face.
Controls and Indicators
Adjustment Indicator The adjustment indicator provides information
on whether an adjustment is being made or the limit of the adjustment
range has been reached.
If you are not at the limit of the control range, (up or down) when you
press a control, the adjustment indicator light will come on.
If you are at the limit of the control range, when you press a control, the
adjustment indicator light will not come on. This indicates that no further
adjustments can be made.
QVision Operations and Installation Guide 2-9
The following table lists the functions of each control:

Chapter 3
CARE AND MAINTENANCE
This chapter explains how to care for and maintain your QVision
Graphics System from Compaq in normal everyday use. It also contains a
troubleshooting guide.
PROTECTING THE MONITOR
To protect your monitor from overheating and other types of damage,
follow these suggestions:
§ Place the monitor at least 4 inches (10 cm) away from the wall.
§ Never cover the ventilation slots with any type of material, including
cloth.
§ Never allow liquid to drip into the monitor.
§ Do not place plants on top of the monitor. Water or dirt from the
plant may fall into the vents.
§ Do not block the bottom ventilation slots by operating the monitor on
a surface that will conform to the bottom of the monitor, such as a
bed, sofa, or rug.
§ Operate the monitor only in a properly ventilated area.
§ Do not expose the monitor to excessive moisture or dust.
§ Never place the monitor on an unstable stand.
§ In a two-monitor system, place the monitors as far apart from each
other as possible to lessen interference between them.
§ Place the monitor away from implements having strong magnetic
fields, such as high capacity transformers or electric motors.
QVision Operations and Installation Guide 3-2
CLEANING THE MONITOR
To clean the monitor follow these steps:
1. Turn off the monitor and the computer.
2. Dust the monitor by wiping the screen and the cabinet with a soft,
clean cloth.
If the screen requires more than dusting, use an anti-static CRT screen
cleaner.
CAUTION: Do not use benzene, thinner, or any volatile
substances to clean the unit. These chemicals may
damage the cabinet finish.
SHIPPING THE MONITOR
To ship the monitor, follow these steps:
1. Turn off the monitor and the computer.
2. Disconnect the signal cable from the computer.
3. Disconnect the power cable from the AC power outlet.
4. Unplug the cables from the back of the monitor.
5. Place the monitor in its original box with its original packing
material.
WARNING: The monitor weighs approximately 45 pounds.
Use care in moving it.
QVision Operations and Installation Guide 3-3
SERVICING THE MONITOR
The monitor is designed to give you a long period of trouble-free
operation. To help extend the useful life of your monitor, follow the
procedures listed below:
§ Do not simultaneously set the brightness and contrast controls at the
maximum levels.
§ Turn the monitor off when it will not be used for an extended period
of time (such as overnight).
If your monitor display is not functioning properly and you are unable to
restore the normal display by adjusting the controls discussed in this
guide, contact your Authorized COMPAQ Reseller or your Authorized
COMPAQ Service Provider.

The following input sync information is presented for technically sophisticated
users who want to connect the monitor to a non-COMPAQ computer. You may
need to provide your own cables or connectors to the computer.
Non-technical users should consult an Authorized COMPAQ Reseller or an
Authorized COMPAQ Service Provider.
ACCEPTABLE SIGNAL
TRANSMISSION SCHEMES
Composite Sync on Green
This scheme uses 3 of the 5 BNC connectors. The other two are not used
and should not be connected.
Video Input Characteristic: Typical input impedance of the videoamps is
75 ohm.
Video Signal Definition: The three video inputs are red, green, and blue
analog signals, where 660 milli-volts is the maximum signal amplitude
above the black level. The green video input signal contains sync
information.
Black Level: The black level is 0.054 volts above the front/back porch
reference level.
Sync Signal Definition: Horizontal and vertical synchronization signals
are integrated onto the green video signal, using RS-343-A voltage levels.
Composite Sync, Separate Analog
Videos
This scheme uses 4 of the 5 BNC connectors. The other one is not used
and should not be connected.
Video Input Characteristic: Typical input impedance of the videoamps is
75 ohm.
Video Signal Definition: The three video inputs consist of red, green, and
blue signals, each with an associated ground, driven into a terminated
line. The video signals are analog, where 0 volts corresponds to black,
and 0.7 corresponding to white, and 1.00 volt is the maximum allowable
signal amplitude above the 0 volt reference.
